DESCRIPTION The doveadm purge command is used to remove
all messages with ref- count=0 from a user’s mail
storage. The refcount of a message is decreased to 0 when
the user (or some administration utility) has expunged all
instances of a message from all mailboxes.

In the first form, doveadm(1) will perform the purge
action for the currently logged in user.

In the second form, the command will be executed for all
users

In the last form, only messages of the given user(s)
will be purged.

OPTIONS Global doveadm(1) options:

-D Enables verbosity and debug messages.

-v Enables verbosity, including progress counter.

Command specific options:

-A If the -A option is present, the command will be
performed for all users. Using this option in combination
with system users from userdb { driver = passwd } is not
recommended, because it contains also users with a lower UID
than the one configured with the first_valid_uid
setting.

When the SQL userdb module is used make sure that the
iter- ate_query setting in /etc/dovecot/dovecot-sql.conf.ext
matches your database layout. When using the LDAP userdb
module, make sure that the iterate_attrs and iterate_filter
settings in /etc/dovecot/dovecot-ldap.conf.ext match your
LDAP schema. Oth- erwise doveadm(1) will be unable to
iterate over all users.

-S socket_path The option’s argument is either an
absolute path to a local UNIX domain socket, or a hostname
and port (hostname:port), in order to connect a remote host
via a TCP socket.

This allows an administrator to execute doveadm(1) mail
commands through the given socket.

-u user/mask Run the command only for the given user.
It’s also possible to use ’*’ and
’?’ wildcards (e.g. -u *@example.org). When
neither the -A option nor -u user was specified, the com-
mand will be executed with the environment of the currently
logged in user.
